Expanding Homegroup Abends Pmview Options

[Swifty]

If I accidentally click to expand "Homegroup" under Open->File (or ->Save for that matter). then PMView fails (as in "PMView PRO has stopped working")

I seem to recall that this started when I upgraded my home PC from an old XP system to Win7 Ultimate on a much faster system. I never had much use for "Homegroup" though. I'm just tired of clicking the wrong "+" and having to start from scratch again. Both x64 and x32 versions fail (3.75 right now)

I've registered this problem with Technical Support, but thought I'd ask here in case anyone has a workaround.

It is quite probable that I've not setup a "Homegroup", but having PMView fail is a bit extreme...
